"Thanks for revealing your strategy," she said in an acid tone.
The absence of fangs and the battery acid blood probably would have saved her life.
The first class include such changes as the alcoholic fermentation of sugar solutions, the acetic acid fermentation of alcohol, the lactic acid fermentation of milk sugar, and the putrefaction of animal and vegetable nitrogenous matter.
It may be prepared by the addition of potassium nitrite to an acetic acid solution of cobalt chloride.
Ignoring the acid tone, Gabriel sat in the chair a few feet from him.
The acid, when distilled slowly, is decomposed and yields a and 0-angelica lactones.
Lister for isolating a pure culture of lactic acid bacterium.
It is universally found that the weights of two bases which neutralize the same weight of one acid are equivalent in their power of neutralizing other acids.
Other yeasts are stated to form sulphurous acid in must and wort.
Cobalt fluoride, CoF 2.2H 2 0, is formed when cobalt carbonate is evaporated with an excess of aqueous hydrofluoric acid, separating in rose-red crystalline crusts.
Pasteur found that, when cane sugar was fermented by yeast, 49.4% of carbonic acid and 51.1% of alcohol were produced; with expressed yeast juice cane sugar yields 47% of carbonic acid and 47.7% of alcohol.
He recommended that yeast should be purified by cultivating it in a solution of sugar containing tartaric acid, or, in wort containing a small quantity of phenol.
He determined the percentages of carbon, hydrogen and oxygen in the sugar and in the products of fermentation, and concluded that sugar in fermenting breaks up into alcohol, carbonic acid and acetic acid.
7 succinic acid, 3.2 glycerin and 1.
Duclaux found that acetic acid is formed in small quantities during fermentation; aldehyde has also been detected.
GALVANIZED IRON, sheet iron having its surface covered with a thin coating of zinc. In spite of the name, galvanic action has often no part in the production of galvanized iron, which is prepared by dipping the iron, properly cleaned and pickled in acid, in a bath of molten zinc. The hotter the zinc the thinner the coating, but as a high temperature of the bath is attended with certain objections, it is a common practice to use a moderate temperature and clear off the excess of zinc by passing the plates between rollers.
On the addition, well stirred, of a small quantity of dilute sulphuric acid, a precipitate of sulphur slowly forms, and during its growth manifests exceedingly well the phenomena under consideration.
3 The surrounding silver was then dissolved by nitric acid, and a platinum wire of extreme fineness remained.
It dissolves readily in strong nitric acid, and the helium contained is thus liberated.
"C'mon, c'mon," she whispered desperately, her throat burning with acid as she struggled to hold down her stomach.
It is an indigo-blue powder, soluble in hydrochloric acid, but insoluble in dilute nitric and sulphuric acids.
Iridium sesquichloride, IrC1 31 is obtained when one of the corresponding double chlorides is heated with concentrated sulphuric acid, the mixture being then thrown into water.
Iridium tetrachloride, IrC1 41 is obtained by dissolving the finely divided metal in aqua regia; by dissolving the hydroxide in hydrochloric acid; and by digesting the hydrated sesquichloride with nitric acid.
Carbonic Acid Gas.
It is a brown-black powder soluble in hydrochloric acid, chlorine being simultaneously liberated.
The barium and magnesium salts of this acid are formed when baryta and magnesia are fused with cobalt sesquioxide.
Electrolysis of a solution in hydrofluoric acid gives cobaltic fluoride, CoF3.
By dissolving it in concentrated sulphuric acid and warming the solution, the anhydrous salt is obtained.
Hot concentrated sulphuric acid also decomposes allantoin, with production of ammonia, and carbon monoxide and dioxide.
Another fact of considerable technical importance is, that the various races of yeast show considerable differences in the amount and proportion of fermentation products other than ethyl alcohol and carbonic acid which they produce.
Certain acid fermentations are of common occurrence.
Moulds have been isolated which occasion the formation of citric acid from glucose.
Acid oxidizing agents, however, completely destroy them.
In "cold galvanizing" the zinc is deposited electrolytically from a bath, preferably kept neutral or slightly acid, containing a io% solution of crystallized zinc sulphate, ZnSO 4.7H20.
